Printed Circuit Board (PCB) - Design, Function & Applications #205273 (License: Personal Use)

This image shows a single-layer green PCB made from fiberglass-reinforced epoxy (FR-4), with etched copper pathways connecting component pads and through-hole vias. The board includes four corner mounting holes and a symmetrical layout optimized for signal integrity and manufacturability. Such PCBs form the backbone of consumer electronics, industrial controllers, and embedded systems.
